New contract, when upgrading

My mother who is retired was advised she is ready to upgrade, she went to the store and got a new phone as per normal - on the same number. She found out on her statement she now pays two monthly fees. When going to the Cell-C store she was advised that they opened a new contract?!!!<br> We have had no success in store or the call Centre. The store attendants advised the matter should be resolved by the call centre. They even told her they receive the same service from the call centre and that your company are known to trick clients like this. The calls at the call centre gets dropped constantly, they advise the matter will be referred. Endless stories! This has been going on for a month.<br> She put a stop order on her account and they have blocked her number - which were expected. Can someone please contact us - me, as her number is now blocked? To sort this issue out?<br> <br>
